Undoubtedly a site of great significance for waterbirds with 10,000-20,000 birds wintering in the late 1980s (although formerly 40,000-50,000). Breeding waterbirds include Botaurus stellaris, Ixobrychus minutus and colonies of other Ciconiiformes totalling 1,000+ pairs. Species of global conservation concern that do not meet IBA criteria: Phalacrocorax pygmeus (breeds), Pelecanus crispus (the last site in Azerbaijan where this species bred; formerly 5-15 pairs, could still survive), Marmaronetta angustirostris (breeds), Oxyura leucocephala (non-breeding winter visitor), Haliaeetus albicilla (non-breeding, 2-3 winter). Other breeding birds include Tadorna ferruginea, Circus pygargus, Francolinus francolinus, Porphyrio porphyrio, Chettusia leucura and passerines.
